Bodhidharma says: “If you speak when you know, Your speech is free. If you’re silent when you don’t know, your silence is tied. If speech isn’t attached to appearances its free. If silence is attached to appearances, it’s tied. Language is essentially free. It has nothing to do with attachment. And attachment has nothing to do with language. Reality has no high or low. If you see high or low, It isn’t real. A raft isn’t real. But a passenger raft is. A person who rides such a raft can cross that which isn’t real. That’s why it’s real.”
